摘要：本实验以燕麦和红曲为主要原料，利用红曲发酵燕麦酿制黄酒。为缩短生产周，提高酒质，便于管理，本试验采用酒药与红曲共酵，并就影响酒质的药曲配比、发酵时间和发酵温度4个主要因素采用单因素试验。并且在测定酒精度、总糖、总酸之后设计进行正交试验，再加入感官评定标准，综合评定出成品燕麦红曲黄酒的理化指标和感官指标，确定最佳的发酵工艺条件，从而探索出一条基本的生产工艺路线：红曲用量10%，酒药用量0.6%，发酵时间为7d，发酵温度为29℃。该条件下发酵的成品酒口清醇，醇厚爽口，色泽红色、清亮透明，呈宝石红色泽，香气幽雅，具有独特风格。20524

Preliminary studies of oats monascus rice wine production techniques
Abstract：This experiment by oat and red kojic rice as the main raw material, using monascus fermentation oats brewed rice wine.To shorten the production week, improve liquor quality, easy to manage, this experiment adopts the collaboration with red kojic rice leaven, and the influence of liquor medicine curve ratio, fermentation time and fermentation temperature in four main factors by single factor experiment.And in the determination of alcohol content, total sugar, total acid after the orthogonal experiment design, add the sensory evaluation criteria, comprehensive evaluation of the finished product oats red kojic rice wine of physical and chemical index and sensory index, the best fermentation conditions were determined, so as to explore a basic production process route: 10% dosage of red kojic rice, dosage of collaboration for 0.6%, fermentation time for 7 days, the fermentation temperature is 29℃.Under the condition of the fermentation product wine taste fresh, mellow and refreshing, colour and lustre is red, clear and transparent, ruby red color, aroma is quiet and tastefully laid out, with a unique style.
